LOCK.

Application filed August 22, 1927. Serial No. 214,642.

My invention relates to locks of the cylinder type, and it refers particularly to a lock in which the cylinder or key-receiving element is adapted to actuate the mechanism for operating the latch bolt and the dead-bolt of the lock.

One object of'my' invention is to arrange the mechanism in a lock of this character so that only a minimum rotary movement of the cylinder or key-receiving element is required for causing the dead-bolt to be extended to its locking position, or for causing the withdrawing of the latch bolt alone or a simultaneous withdrawing of the latch bolt and the dead-bolt, and that thus the lock may be quickly locked or unlocked by the proper key therefor.

A second object of the invention is to construct a lock of this character so that,

when the dead-bolt is extended to its looking position, it also locks the latch bolt and thereby virtually converts the latter into a dead-bolt, which can not be forced to an unlocked position from the outside of a door, having the lock applied thereto, except by a proper key for the look.

A third object of the invention is to construct a lock of this character so that, when the lock is applied to a door, the lock mechan ism, even if the door is closed, may be set either for allowing or for preventing the opening of the door from the outside without a proper key for the lock, and

that the lock therefore in comparison with any lock, whichfor these purposes is provided with elements, operable only from the inside edge of a door, saves much time for aperson and relieves him of a great deal of annoyance in thus setting the lock mechanism.

A fourth object of the invention is to provide a lock of this character with a unitary element, which has actuating means in connection therewith so as to be normally'adapted to hold all of the tumblers depressed within the cylinder and to co-operate with the tumblers for preventing the rotation of the cylinder except by the proper key, the unitary element and itsactuating means thus taking the place of a plurality of auxiliary tumblers and the individual springs therefor and thereby simplifying the lock construction and causing the locking action to be more dependable than in looks of this character-heretofore known.

A fifth objectof the invention is to construct a lock of this character, in which the latch bolt and the dead-bolt and the op erating elements directly connected therewith, as well as their housings, are contained in one part attachable to the side edge of the door, and certaineleinents of the operating mechanism for the latch bolt and the dead-bolt are contained in a part attachable to one side of the door, while certain other elements of the operating mechanism are contained in a third partattachable to the opposite side of the door, so that the parts may be quickly arranged in lock-operating positions and, when the door is provided with suitable cut-out portions, the

7 parts may be quickly and easily applied in their respective places for effecting the operation of the lock from either side of the door, and that thus the lock may be attached to a' door even by an unskilled per-- son.

A sixth object of the invention is to construct a lock of this character so that the lock may be quickly and easily applied to doors of a different thickness, and so that the look, if required, may be removed from one door and fitted to another without necessitating the change of any partor parts of the lock.

A seventh object of the invention is to construct a lock of this character so that it is necessary to cut out only a minimum portion of a door in order to enable a person to attach the lock to the door, and that the door is not weakened thereby to any appreciable xtent.

An eighth object of the invention is to construct a lock of this character so that a large number of the parts thereof may be made of pressed metal and that thus the lock can be cheaply manufactured and, consequently, can be sold at a very low price.

With the foregoing and other objects in view, my invention resides in the combination and the arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed may be made within the scope of the appended claims without departing from the spirit of the invention.

I

.An embodiment of the lock of my invention is in the drawings indicated as a whole by thenumeral 10'. This lock may be ap-' plied to a door 11, of which only a portion is shown in Figures 1, 2, 3, and 4, by providing the door with suitable cut-out portions for receiving respective parts of the lock therein- Of these cut-out portions,

three portions 12, 13 and 14 are preferably cylindrical in form andarranged in alignmentavltll one another at a sultable distance fromthe side edge of the door, the latter two cut-outportions extending through the door from the 'front to the back thereof, while, the

portion 12-is preferably counterbored only partly through thedoor from the front side thereof. A fourth cut-out portion 15. ex-

' tends from the edge of the door between the sides thereof to the intermediate cylindrical portion'l3 and is of a suliicient width'for accommodating the respective latch-bolt and dead-bolt housings 16 and 17 of the lock 10.

These housings are preferably made of sheet metal and are respectively formed by two side sections 18, 18', and 19, 19, which at their outer ends are respectively provided with aligned flanges 20 and'21, and a plate 22, provided at each of its side edges with a return bend 23, is adapted to be slipped over the flanges, while one section, for instance,the section 18, has an inner end portion 24, which overlaps the inner end portion 25 of the section 19 and is formed with a lug 26 fitting into a corresponding opening in the section 19, so that, when the lug is snapped into the opening, and, when the plate 22 is shipped over theflanges 20 and 21, each of-the housings 16 and 17 constitutes a unitary element and that the housings are in a fixed relation to each other. The

plate 22 is further provided with respective openings 27 and-28 in order to allow the latch-bolt 29 and the dead-bolt 30'to slide freely therein, and both the plate and the flanges have suitable registering openings for receiving the; fastening means, such as 00 screws 31, which are screwed'into the side edgefof the door 11 and thus securely hold the housings within the cut-out portion 15, the door being recessed so as to fit the plate" 22 and to cause the outside of the'plateto be flush with the edge surface of the" door, as shown in Figure 3. v

In the latch-bolt housing 16 is slidably fitted aplunger 32, which is provided with an inner end wall 33 and an outer end wall 10 34, and another plunger 35 is also slidably fitted in the housing and is arranged in a slidable relation to the plunger 32 between the end walls 33 and 34thereof. At its inner end the latch bolt 29 is provided with a stem 36, which extendsslidably through an opening n the end wall 34.- of the plunger 32and 1s near its free end provided with a 'recessedportion 37. This recessed portion is adapted to bereceived 1n a slot formed 11o in an end wall 38 of the plunger 35 so that, in fact, the stem may be considered as unitary with I the wall 38 and thus, when the plunger35 is re eiprocatedin the housing 16,

a proportional reciprocating movement is at the same time lmparted to the latch bolt 29. A 'coilsprmg 39 1S placed around the stem I 36 and between the wall 3% and the inner end of the latchbolt so as to hold the latch bolt normally extended outward fromethe plunger 32 and at the same time to cause the wall 34 of the plunger 32 to contact the wall 38 of the plunger 35. vBy this arrangement the latch bolt is adapted to fol low the reciprocatmg movements of the plunger 32 in the housing 16. -Another coil spring 10, somewhat stronger than the spring 39, is placed in the housinglfi between the inner end wall 33 of the plunger 32 and the inner end portion 25 of the hous- 13c ing for the purpose of normally forcing the plunger 32, and therewith also the plunger and the latch bolt, outward.

For operating the latch bolt from the inside of the door 11, the housing 16 is laterally provided with aligned openings, in which are rotatably mounted the respective ends of an operating element 41 having longitudinally therethrough an opening, so that the operating element may be fitted upon a door-knob shaft 42, the shaft for the convenience of illustration being shown as square in cross section, a-nd the openingin the operating element being correspondingly shaped, although it is understood that any other practical way of arranging the operating element in a slidable but nonrotatable relation to the shaft may be adopted. The

operating element is provided with an arcuate portion 43, which is concentric with the shaft 42 and has at its ends shoulders or lugs 44 and 45, and cut-out portions 46 and 47 are respectively formed in the top and the bottom of the housing 16 in order to allow a free movement for the arcuate portion, while in the top and the bottom of the plunger 32 are formed respective cut-out portions 48 and 49, the respective end edges 50 and 51 of which are adapted to contact the lugs 44 and and, together with the lugs, serve as means for limiting the outward movement of the latch bolt so that only the portion that has the inclined face 52 thereon will extend beyond the plate 22 when the plunger 32 is forced outward by the spring 40, and also as means, whereby a partial rotary movement of the door-knob shaft 42 will cause an inward movement of the plunger 32,,a-s well as the plunger 35 and the latch bolt against the tension of the spring 40. r

A mounting plate 53 for certain parts of. the lock 10 is adapted to be applied to the inside of the doorll. Preferably, the plate is for this purpose provided with a de pressed portion 54, which at its periphery fits the inner end of the cut-out door portion 13, while the plate otherwise is suitably formed so as to extend with an end portion 55 over the cut-out door-portion 14.

Another mounting plate 56 for certain parts of the lock is adapted to be applied to the outside of the door. This plate, in addi tion to extending over the cut-out door portions 13 and 14, also extends over the cutout door portion 12 and has therein an opening in which is fitted the reduced portion 57 of a cylinder housing 58, while a shouldered portion 59 of the housing bears against the outside of the plate. The door portion 12 is preferably made to fit the reduced portion 57, and the latter is closed at the rear end of the housing by a wall 60,

outside aninternall'y threaded boss 61.] A

screw 62, for which a clearance hole 63 in axial alignment with the boss is drilled through the door, is adapted to be screwed into the boss and has thereon a washer 64, which is preferably provided with prongs 65 for non-rotatably engaging the inside of the door, so that, when the screw is screwed home into the boss, the plate 56 is securely held at one end to the outside of the door. To the plate 56 is also preferably secured a threaded stem 66, which extends from the inner side of the plate and at right angles thereto so as to be in alignment with an opening in the depressed portion 54 of the plate 53, and an elongated female screw 67, provided with a slotted head 68, is adapted to extend through the opening and to be screwed upon the stem 66 in order to cooperate with the screw 62 in holding the plate 56 securely in its required position on the outside of the door 11.

In the housing 58 is a longitudinal bore eccentric to the housing and extending from the front end to the rear wall 60 thereof, and in this bore is rotatably mounted a cylinder 69, which is provided with a suitably formed slot 70 for receiving the correspond ingly shaped shank 71 of a key 72 therein. Towards the periphery of the cylinder 69 the slot 70 is widened and is adapted to register with acorrespondingly wide slot 73 formed radially in the cylinder housing 58, as shown in Figure 4. In the slot 70 and at the ends thereof are respectively mounted master tumblers 74 and 75, and between these tumblers are mounted other tumblers 76. Each of the tumblers 74, 75 and 76 comprises a key-contacting portion 77, which slidably engages the narrow part of the slot 70, and a shouldered port-ion 78, which is slidable in the slot 73 and the wide part of the slot 70, so that all of the tumblers are limited in their inward movement into the cylinder by the contact of the shoulders 78 with the bottom of the wide part of the slot 70. The key-contacting portions 77 are preferably beveled at-their ends wherever necessary, and the key shank 71 is also beveled in corresponding places in its tumbler-contacting edge, except at the re spective master portions 79 and 80 thereof, in order to allow the shank to slide freely into and'out of the slot 70.

An escutcheon 81, conforming to the contour of the plate 56, is fixed to the plate by any suitable means. For instance, lugs 82 may be formed in appropriate places on the inside of the escutcheon, and openings 83 may be correspondingly formed in the plate for the reception of screws 84 which are screwed into the lugs. 'Preferably, the screws 84 are provided with fiat heads, and the openings 83 are countersunk accordingly so that the screw heads will not protrude beyond the door-contacting surface of the 71 but also sufficiently small so that the 1 cylinder and the tumblerszean not move therethru out of the housing 58.

' In the slot 730i the cylinder housing is elongatedblock or element 87 the ends 88 of which are preferably rounded. This block is mounted so that it is'adapted to slide freely into or out of the wide partof the slot 70 and laterally to'engage the shouldered portions 7 8 of the tun1blers7t, 7 5 and 7 6, and it extends: so that it has a suificient end play between the rear wall of the cylinder housing and the portion 85 of the plate 81 for allowing the block'tobe rocked and thereby adapted to enter the wide part of the slot with either of its ends 88. Means for urging the block 87 towards the tumblers is provided in the form of a curved leaf spring 89, which is mounted in the slot '73 and with its ends bears against the block near to the ends of the latter, while the intermediate curved portion of the spring bears against the wall90, by which the slot is boundedlongitudinally opposite to its opening toward the cylinder 69. By.

this arrangement the tumblers are forced inward into the cylinder, so that, when the key 72 is withdrawn from the cylinder, the shouldered portions 78 of the tumblers bear against the bottom of the. wide part of the 7 slot 70, and the block 87 thusextends longitudinally both in the widepart or the slot 70 and in the slot 73 and thereby normally prevents rotation of the cylinder. It is also evident that, by thisarrangement, ifan improper key is inserted into the cylinder, the keyeither will cause the tumblers to depress the' block more at one end than at the other, or will cause the tumblers to force the block entirelyout of the wide part of the slot while the tumblers, themselves with theirshouldered portions 78 enter the slot 78, so that the tumblers and the block always cooperate in preventing the cylinder from being rotated by a wrong key. Again,

' by the insertion of theproper key into the cylinder, the tumblers are caused to depress the block so that it is inits entire length out of the wide part'of the slot 70, while the shouldered portions of all the tumblers at the same time are retained therein, and thus the cylinder readily can be rotated in either direction by the key.

Diametrically opposite to the slot 73, the shouldered portion 59 of the cylinder housing 58 has therein a cut-out portion 91,

V Y which preferably extends from the front as of the housing rearwardnearly to the plate 56 and is ,laterally'bounded by'walls 92 and 93, and an arm 94,-integral with'the cylinder 69, projects radially from the latter through and beyond this cut-out portion inorder to allow the arm a certain lateral swinging movement and atthe same time, by the contaet of the arm with the side walls92 and 93 toallow only a partial rotary-movement of the cylinder. The arm 9 1 has integral therewith a pin 7 95, projecting rearward therefrom between the. respective upper ends of an operating lever 96 and another lever '97, these leversbeing mounted on a common pivot secured to the plate 56. V

In the escutcheon 81 is an opening99 adapted to have tulcrumed therein a latch lever 10, which extends inward tlrough a sufiiciently large opening 101 in the plate 56 for allowing the. necessary swinging movement of the lever. and is outside of the escutcheon provided with a thumb-hold 102. Slightly below the thumb latch lever the escutcheon vhas secured thereto by means of a nut 103 the upper end of a conventional door handle 104:. A bell-crank lever 105 is suitably pivoted to the plate 56, as shown at 106, one arm of the bell-crank lever being adapted to restupon the latch lever 100, while the other arm thereof extends upward and is at its end pivotally connected with oneend of a link 107. The other end normally held at the-left endof the slot in substantially. vertical alignment with the pivot98' and the pin95 on the arm 9% when the cylinder 69' is in ,itsnormal or locked position, as shown in Figure 4, and such that, when the lever 96 is swung in a contraclockwise direction, the swinging move 'ment is limited by the contact oi the pin 108 with theplate 56' at the right end of the slot109. This contra-clockwise swinging of the lever 96 -is-efi.ected in either of two ways viz: by the rotation of the cylinder 69 in av clockwise direction, or by the depression of the thumb-hold 102 so as to raise the inner end of the latch lever 100 upward. lVhe'n the cylinder is rotated in the aforementioned ydirection,.the pin 95 on the arm 94, by its contact with the up per end of the lever 96, forces the lever to swing in the contra-clockwise direction until the movement of the cylinder is stopped by the contact of the arm 94 with the wall 92 simultaneously with the stopping of the levers movement by thecontact of the pin 108 with the plate 56 at the right end of the slot 109. Again, by the-elevation-..o f the inner end of the latch lever 100, the bellcrank lever 105 is swun in a clockwise direction and communicates its motion to the lower end portion of the plate 53, and ashouldered bushing 113 is rotatably mounted in the latter opening so as to bear with its shoulder against the inside of the plate 53. A shaft 114, preferably square in cross section, as shown in Figures3and 4, is fitted in the bushing and is adapted to extend inward therefrom inthe cut-out door-portion 14, and the shaft 111 has formed longitudis nally therein a correspondingly square-walled opening 115, so that the shafts 111 and 114 may be slidably joined'and may be considered as virtually splined to, and cooperating with, each other in the cut-out portion 14 when the plates 53 and 56 are secured to the door 11, as shown in Figure 1.

Fitting the contour of the plate 53 is an escutcheon 116, which has an opening therein adapted to register with the opening in the end portion 55 and with the opening 112 in the plate 56, and in this escutcheon opening is rotatably mounted the inner end of a knob 117, which is suitably fixed to the outer end of the shaft 114. The knob is preferably of the wing type and has ashoulder 118 adapted to bear against the outside of the escutcheon, whilea pin 119 is driven through the shaft 114 adjacent to the shouldered bushing 113 so as to permit rotation of the shaft and at the same time to prevent the bushing from sliding inward into the cut-out door-portion 14 and to hold the lower part of the escutcheon in engagement with the end portion 55 of the plate 53.

Preferably, the inner end of the shaft .42 is threaded and has a nut 120 tightly fitted thereon, and the shaft is adapted to extend through a clearance opening 121 in the depressed portion 54 of' the plate, 53 and through an opening 122 formed in the escutchen 116 in axial alignment with the opening 121 and adapted to have rotatably mounted therein the inner end of a door knob 123, which is provided with a shoulder 124 adapted to bear against the outside of the escutcheon. The shaft is preferably threaded for some distance at its outer end. and the knob is correspondingly threaded and screwed upon the shaft, so that, by

7 means of the nut 120 and the knob 123, a

sufficient end play of the shaft for allowing a free rotation thereof may be effected, while at the same time the nut and the knob cooperate in holding the upper part of the escutcheon in engagement with the upper part of the plate 53. A set-screw 125, threaded into the knob so as to be adapted to engage one of the flat side faces of the shaft, further serves to hold the knob in its adjusted position upon the shaft.

It should be noted that the escutcheons 116 and 81, when attached to the respective plates 53 and 56, form therewith respective housings 126 and 12'", adapted to hold certain operative parts of the lock 10 therein and to allow these parts freedom of movement in the housings. Thus, the shaft 111 has secured thereon in the housing 127 and between the plate 56 and the bearing 110 a locking lever 128, which extends upward from the shaft and to one side of the latch lever 100. At its free end the locking lever 128 has integral therewith an arm 129, preferably arcuate and concentric with the shafts 111 and 114 and adapted to extend under the lower end of the lever 97 and over the latch lever so as to prevent the latter from operating the lever 96 when the lever 128 is swung towards the latch lever. An upward extending lip 130, adapted to be in the path of the lower end of the lever 97, is formed at the end of the arm 129. By this construction, when the lever 97 is swung in a clockwise direction, it will engage the lip and thereby swing the lever 128 so that the arm 129 comes in the path of the latch lever and that thus the latch bolt 29 can not be operated from the outside of the door 11 by the latch lever.

In the housing 126 and on the bushing 113 is rotatably mounted a lever 131, adjacent to the end portion 55 of the plate This lever has fixed at its free end a pin 132, which extends inward from the lever through an arcuate opening 133, formed in the depressed portion 54 of the plate so as to allow the pin to travel freely therein and at the same time to limit the swinging movement of the lever. The pin 132 is of such alength that, when the plates 53 and 56, the latch-bolthousing 16 and the dead-bolt housing 17 are secured to the door 11, as described, the pin extends through an opening 134 formed in the inner end of a bar 135, which is fixed to the dead-bolt 30 and extends inward therefrom into the cut-out door-portion 13, the opening 134 preferably being elongated so as to allow the pin 132 to move transversely of the bar and to cause a reciprocating movement of the deadbolt by the swinging movement of the lever 131. In the housing 126 is also mounted alongside of the lever 131 another comparatively short lever 136 upon the shaft 114 and in a nonrotatable relation thereto. A pin 137 is fixed to thevendofthe lever '1 36 extends inward therefrom"with freedom of movement erably so asto be frictionally slidable' thereyon, a sleeve 139. This sleeve has integrally formed thereon ala'teral arm 14 the end 141 of which is adapted to extend down ward through the cut-out portion 16 in the latch-bolt housing 16 and; into an opening 142' formed in the top of the plunger 35. Thus,,if it isassumed that the lock 10 is viewed from the outside of the doorll, upon a rotary movement of the cylinder 69 111 a clockwise direct on and upon theconsequent swinging movement of the lever 96 in the contra-clockwise direction, as before described, the lever will 'pull the plunger and therewith also the latclrbolt 29 inward into: the housing 16 against the tension of the 'spring39; At the same tim'e, the: spring 40 will counteract an inward movement of 30 the plunger P 32 so that, upon the return movement of the cylinder towards 1ts normal or locked position, the spring 39 will cause the lever 96 to swing back in a clockwise dif rection andthereby will force the plunger '35 outward and therewith also the latch bolt to its fully extended position, until the move mentsof the'latch bolt and the plunger 35 are stopped by the contact of the latters wall 38 with the wall3tof the plunger 32. The dead-bolt housing 17 has secure:

' thereto, preferably to the bottom thereof, a "spring14:3,provided at its end with a tongue 14,which extends through an opening in thebotiom oilthe housing and is-adapteo to engage, and to snap into and out of,c'av1ties 1415 and 14:6 formedinthe dead-bolt 30, the

tongue engaging the cavity 145 for holding the dead-bolt in its receded or unlockedposition, as shown in Figure'3, and engaging the 6111 1133 146 for holdmgr'the deiad-bolti n 1t-s extendedor lock ng position. Near its inner, end and at its top the dead-bolt has fixed thereto afpin 1 1'? which extends through i registering longitudinal slets 1418 and 149 formed respectively in the top of the dead-bolt housing and in thebottoi'n oi the lat'eh bolthous ng, the pin belng adapted to contactthe inner ends ofthe slots when thedead -bolt is fullyrwithdrawu into its housingand'to contact the outer ends of the slots whenthe 'deadebolt is in its fully extended or looking position, and] the latch bolt being formedwith end portions 150 and, 151 so that it may be reversed in its housing andin either of its positions maybe adapted to grosses contact the pin and thereby to move the dead-bolt, and that, when the latch bolt is fully withdrawn into its housing, the deadbolt is also moved to its fully receded or unlocked position in 'the'housi'ng '17 v The relation of the levers'128 and 136 to each other is such that when the lever 136 is swungso that the pin 13'? is at the extreme left of the slot 138 in the lever 131, and that the latter lever is also ithereby swung until the pin 132 is at the extreme left of the are cuate opening 133, if it is assumed that the lock 10 is viewed from the inside of the door 11, as, shown in Figure 2-the lever 128 is swung to its normal position or its extreme position away from the latch lever 100; that is, to the right of the latter, if it is assumed that the lock is viewed from the outside of the door, asshown in Figure 4.

From the foregoing description, it is clear that the lock 10'may be quickly and easily a olied-to doors of reatl var i'n thick- C! y D ness. Afte'r the latch and dead-bolt housings havebeen secured inthe cut-out portion 15, the shaft 412, with the nut 120 at its inner end, is inserted into the operating element 41 the housing'127, with its respectiveloclr operating parts assembled therein, is placed in the proper position on theoutside or the door, and the end 141 of the arm 140 on the sleeve 139 is inserted intothe opening 142 inthe plunger 35. The mountingplate 53, with its respective lock-operating parts assembledthereon, is thereafter )laced in the proper position on'the inside of therdoor, so that the shaftrlli engages the shaft 111, and the pin 132' engages the slot 134 in the dead-bolt bar 135. The screws 62 and 67 are thenrscrewed home, so that the housing 127 is'fixedf to the outside of the door while the -mounting plate 53 is hired to the inside thereof.

After this, the escuteheon 116 is slipped over the:'shafts 42 and 11 1, and the door kn'ob'123 issecured in the proper position on the'sl1aft"4;2 by the. set-screw 125, while the wing knob 117 may be's'ecured in the proper position upon the shaft 114 by a setscrew 1 2, so that the escutcheon 116 is retainedbyitheknobs 117 and. 123 upon the mounting plate 53 and thereby, com-- pletes thefhousing'126; in which the levers 131 and "13.6 operate. H 7

When a door 1-1, having a lock 10 of my in vention secured thereto, as "described, is closed, it is normally'held in a latch engagement with-a door-frame member, which 'is indicatedoby a dot-and-dashline-in Figure 3, by the normally extended'i latch bolt 29.

,A person is enablechiby simply'turning the knob 123 in either direction, to withdraw the latch bolt and thus easily to open the door from theinside thereof. "The 'dead bolt, if it is in itsextended or locking position, may also be withdrawn in 'thesame manner toget-her with the latch bolt by the turning of lation of the. latch side of the door.

in its extended or locking position.

ing of the door from the outside except by'a proper key 7 2 for the lock, a person turns the wing knob only until the pin 137 on the lever 136 reaches the right end of the slot 138 in the lever 131, as'viewed from the in- .lhe tongue 1 14 on the spring 143, by its engagement with the cavity 145, will then sufficiently resist an outward movement. of the dead-bolt so as to cause the person to stop the turning movement of the wing knob, unless it is desired to move the dead-bolt to its extended position and thereby to lock the door. When the lever 136 is swung in this manner, the lever 128 is at the same time swung suiiiciently far toward the latch lever 100 for causing the arm 129 to come into the path of the latch lever. and thus effectively to prevent any movement of the latchbolt by the 1nanipulever from the outside of the door. j v

It'is understood from the description regarding the operation of the cylinder 69 that a personmay open the door from the outside by first inserting a proper key into the cylinder and then turning the cylinder in a clockwise direction, thus effecting the swinging of the lever 96 in a contra-clockwise direction, as viewed from the outside of the door, but it should also be observed that, while by this movement of the cylinder the latch bolt is withdrawn and the door is opened, the 129 still remains in the path of the latch lever 100, since the movement of the cylinder in the aforementioned direction, when the lever 136 has been swung, as de: scribed, does not effect a movement of the shaft '111 to which the lever 128 is fixed. The door may thus be slammed shut repeatedly without changing the position of the arm 129, so that, as long as the lever 136 remains in the position referred to, key must be used, as described, in order to withdraw the latch bolt and thereby to enable a person to open the door from the'outside.

When a person desires, not only to latch the door but to lock it from the inside, he simply continues to turn the wing knob 117 in the aforementioned direction and thereby swings the levers 136 and 131 until the pin 132 reaches the right end of the arcuate opening 133 and thus stops the movement, while at the same time the tongue 14% on the spring 1 13 snaps'into the cavity 146 in the dead-bolt and thereby retains the latter The lever 128, of course, is also by this continued movement swung farther toward the latch lever 100. Then, in order to open the door from the outside, a person, after having inserted a proper key into the cylinder, turns the latter in the same manner as before described in regard to the operation of the latch bolt from the outside of the door, thus swinging the lever 131 back to its normal position, with the pin 132 at the left end of the slot 133, as shown in Figure 2, and thereby simultaneously withdrawing the latch bolt and the dead-bolt from their extended positions, while at the same time the lever 136, on account of the play of the pin 13'? in the slot 138, is swung back only to the position it is caused to assume for preventing the operation of the latch bolt from the outside of the door, as before observed.

From the outside of the door, a person may turn the cylinder with a proper key therein in a contra-clockwise direction, thus causing the lever 97 to swin the lever 128 towards the latch lever 100 until the movement is stopped by the contact of the arm 91 with the wall 93, as-befo re described, and thereby locking the door, or a person may turn the cylinder only partially in the same direction in order not to extend the dead-bolt but merely to hold the door in a latch engagement with the door-frame member in the manner explained in regard to the operation of the levers 136, 131 and 128 by the wing knob 117. In either case, the door is opened from the outside in the same manner as it is opened after having been secured from the inside by the operation of the wing knob.

hen it is desired to leave the door unlocked so that it may be opened from the outside by the depression of the thumb-hold 102 on the latch lever, the wing knob is simply turned in a contra-clockwise direction until the lever 131 is swung back to itsnormal position by the lever 136, so that the pin 132 is moved to the left end of the arcuate opening 133, as shown in Figure 2, and that the lever 128 also is swung back to its normal position, with the arm 129 out of the path of the latch lever, as shown in Figure 4.

' As before observed, the latch bolt is shown as provided at its inner end with portions 150 and 151 adapted to contact the pin 1 17. lhis, of course, is merely illustrative, since the latch bolt obviously can be constructed in various ways so as to allow the full eX- .tension of the dead-bolt and to be instrumental in forcing the withdrawing of the dead-bolt into its housin and also to allow a reversal of the latch bolt, according to he positioning of the door to which the lock is applied. It should also be noted that, if the latch bolt is reversed from the position shown in the drawings, the positioning of the housings 126 and 127 will be changed accordingly, with a consequent reversal of the operatlon of the lock mechan1sm.
